Based on early feedback, looks like 24 or so cars (you don't know how much I hate predicting car count). We've talked to 14 from around Illinois so far today and Andy with WAR in Missouri says he currently thinks 10-12 are coming from there. I'll put some names out a little later after some more confirmation.

EDIT: Now approaching 30. So we are going to bump this to $1,000 to win from WAR's normal $800. See, good things can happen when drivers stay in touch with their race tracks and we can let fans know in advance what kind of show they can expect instead of guessing at it.
